How to change toolbox P/L colors

 
How to change toolbox P/L colors to black, the basic is red for negative and blue for positive i want to make it only black iv seen it before on other people is it a script or what pls help 
 

Update to my previous post...

I have not found a way to set the colors of negative nor positive values in the MT5 terminal. Based on what I've found, there are only read only functions for those elements of the terminal.

Therefore, I suspect that the screenshots that you mention are perhaps the result of pc text display settings, pc high contrast settings, or a custom pc reconfiguration app (risky).
